`SP,EC!IFICA'JJION forming part of Letters Patent No. 291,453, datedJanuary 1, 18i4` application inea May laissa. (No model.)

`.To all whom, it may concern:

Be a known that I, JOHN c. winmix., of

. Union City, in the 'county of Obion and State of Tennessee, haveinvented a new and Improved Broadcast Seedsower, of which the followingis a full, clear, and exact description.

My invention consists of improvements in the construction of thegear-supporting frame,

and in the arrangements of 'the gears of a broadcast sower, consisting,essentially, of a hopper with a rotating cross-spout mounted on theupper end `of a staff connected with the gear-frame, and having afoot-rest to be supported in a strap carried overthe shoulder of theoperator, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

" which similar letters of reference indicate cordistributed, taken onthe line fr c of Fig. 1.

For thegear-frame I provide two thin T- plates, of which a representsthe head and b the stem, which plates are provided with the studs c andd on one side of the head c, and one head has the step-bracket c.Usingthe heads a of these plates for part of the staff, as well as thegear-frame, I connect said head at one end with the wood step-loiecef,and at the other end with the lower end of the wood section g of thestaff, by bolting the plates to op; posite sides of said step and staffat h and i, so that said step and staff and also the studs c and dmaintain the plates sufliciently apart to provide space in which toarrange the drivinggear, the outer ends ofthe parts b of the platesbeing curved, so as to :meet and form separating-studs, substantiallylike studs c, to

` be clamped together by bolt j, and said ends are materially widened,as shown at k, to form a practicable handle by which to manipulate themachine. Between the horizontal parts b of these plates I arrange amaster toothed driving-wheel, Z, with a crank, m, for driving it, andbetween the vertical parts c of said plates, where they join plates b, Iarrange a `spur-pinionm., and a bevel intermediate driver, o, on oneshaft or pivot, to be turned by the driving-wheel. Z, gearing with thepinion n, and to turn the shaft p by the bevel-pinion q, said shaftbeing supported in the bracket e for a step, and extending up throughthe staff g and connecting with the cross-spout s, which is to berotated thereby to discharge the seed out of its ends by centrifugalforce, the seed being received into it from the nozzle t of the hopper uthrough the opening o in its upper side. For closing this nozzle toprevent the fall of the seed into the cross-spout when the machine isnot in motion, and also to regulate the flow of the grain according tothe 'speed of the machine, I now propose to have a gravityvalve, fw,located under the nozzle and connect'ed by an arm, sc, with a pivot, y,from which said arm projects outside of the cross-spout a suitabledistance, and carriesacounterpoise, c, which hangs nearly vertical when.the machine is at rest and keeps the valve closed, but

i will rise by centrifugal force when the machine is set in motion andopen the valve.

At c', I have arranged a plate which bows outward from the gear-frameabove and below the projecting side of the counterdriver o for` a guardto the wheel and for a bearer to rest in the left armpit of theoperator, while the step f rests in thepocket of a shoulderstra-p on the`left side of the wearer, and the handle 7c is grasped in the lefthandto press the bearer c into the armpit for securing the machine inposition. The right hand is then used to work the machine by the crankm. The studs d are notched at the meeting ends for a bearing to theshaft p, and the staff g has a hole through its longitudinal axis forsaid shaft. This arrangement makes a simpler, more compact,

and better working machine than the pulley and-belt gear heretoforeemployed. makes a simple contrivance for the construction of thegear-frame, and the gravity-valve for letting on and shutting off thefeed is more simple and positive in itsaction than the device heretoforeused. l

Having thus described my invention, I claim as new and desire to secureby Letters Patent-` 1. The gear-frame and staff of a broadcast sewer,consisting of the T-plates a b, step f, and wood staff g, boltedtogether, the plates It also IOO having stop-studs c d 7c, also-step-stud e, and having thefpivot-bearings of the gear formed in them,substantially as described.

2. The stop-studs k of the parts b of the gear-frame plates, extendedtransversely to said parts b to form a handle for holding the machinewhen in use, substantially as described.

3. The combination, in the gear-frame and supporting-staff of abroadeastsower, of plates a b, handle 7c, and the guard a, substantially asdescribed. Q

4. The combination, in the supporting and driving gear of a broadcastseed-sower, of the T-plates a b, bearing studs c d e, step f, staff g,driving-wheel Z, pinion n, bevel-Wheel o,

pinion q, and the shaft p, said shaft being arranged in the staff' gandhaving the cross` spout'attached to it, substantially as described.

5. The combination, with the revolving cross-spout s and nozzle t, ofthe valve w and bent lever x, pivoted to said spout, and having saidvalve and the counterpoise z secured directly thereto, the said leverextending through and to the outside of the said spout, 25 essentiallyas shown and described, and for the purpose set forth.
